Definitions

  • This invention relates to vehicle engineering, and more particularly to the construction of railway wheels.
  • a wheel construction that has found a wide application includes a wheel rim and a hub conjugating with a disk interposed therebetween, the medium longitudinal axis of the disk having the form of an inclined straight line, the disk having rectilinear generating lines conjugating with the configurations of the rim and hub by radius curves, conjugation at the outer side of the rim and at the inner side at the hub being effected by two interlinked radius curves of reverse curvature.
  • a railway wheel (cf., SU, A, 1,109,324) comprising a rim and a hub conjugating with a disk interposed therebetween, the median longitudinal axis of the disk configuration being made up of rectilinear portions vertical at the side of the rim and inclined at the side of the hub, and a curcilinear portion disposed between the rectilinear portions and made up of two radius curves of reverse curvature, the curvilinear generating lines of the disk conjugating with the configurations of the rim and hub by radius curves, whereas areas defined by dissecting the disk by axial cylindrical surfaces being equidimensional, and the median longitudinal axis of the configuration of the disk is offset at the hub relative to the median longitudinal axis of the configuration of the hub toward the inner side of the wheel.
  • this wheel is also not free of some inherent disadvantages. Among them are substantial radial rigidity and residual stresses, relatively high tangential and radial stresses in the transition zones and, most disadvantageous, very highly stressed state of the disk during prolonged braking.
  • the present invention aims at providing such a construction of a railway wheel in which the configuration of the disk would ensure mutual compensation of stresses arising in the wheel as a complex load is imparted thereto.
  • the aim of the invention is attained by that in a railway wheel comprising a wheel rim and a hub conjugating with a disk interposed therebetween, the median longitudinal axis of the disk configuration having rectilinear portions with curcilinear portions disposed therebetween, the disk having curvilinear generating lines conjugating the configurations of the rim and hub by radius curves of a radius determined from the expression
  • the cross sectional area of the disk defined by cylindrical secant surfaces coaxial with the hub being equidimensional, whereas the point of conjugation of the median longitudinal axis of the disk with the hub is offset from its middle and the median longitudinal axis of the disk configuration having rectilinear portions with curvilinear portions interposed therebetween, the rectilinear portion of the median longitudinal axis of the disk configuration at the side of the rim conjugating with the first curvilinear portion described by the expression
  • L is the length of the hub
  • H is the magnitude of offset of the median longitudinal axis of the disk relative to the midpoint of the hub
  • d is the outer diameter of the hub.
  • the proposed railway wheel was service-tested and has shown an average reduction in stresses in the most critical zones by a factor of 2, the susceptibility of the wheel to displacing from the hub during braking being reduced by one third.
  • FIG. 1 illustrates the configuration of a railway wheel according to the invention
  • FIG. 2 shows the construction of the wheel configuration according to the invention
  • FIG. 3 shows distribution of stresses in the wheel disk
  • FIG. 4 shows distribution of stresses in a known plane-conical wheel disk
  • FIG. 5 shows distribution of stresses in a known curvilinear wheel disk.
  • the proposed railroad wheel comprises a rim 1, a disk 2; and a hub 3.
  • the shape of the disk 2 conjugates with the shapes of the rim 1 and hub 3 by radius curves of a radius ranging from 0.04 D to 0.06 d whereas the curvilinear part of the fisk configuration is made up of three portions:
  • AE is the curvilinear portion of a median longitudinal axis 4, the point E being obtained at the intersection of the third curvilinear portion CE with a straight line 5 running in parallel with the median longitudinal axis 6 of the hub 3 and offset therefrom toward the outer side of the wheel to a magnitude
  • Described hereinbelow are examples for designing the shape of a railway wheel according to the invention.
  • FIG. 2 represents, apart from the conjugate points of the curvilinear portions, intermediate points E 1 , E 2 , C 1 , B 1 , B 2 and B 3 .
  • Thicknesses of the disk are calculated from the condition of equidimensional areas of the disk dissected by the cylindrical surfaces according to the preset thickness in a section passing through the point A. Actual values of the thickness of the disk at point A-h A are within a range of 15 to 25 mm depending on the wheel designation. Therefore, the initial area
  • the thickness of the disk at points E 1 , E 2 , C 1 and B 1 will be 32 mm, 24.8 mm, 22.6 mm and 19.1 mm, respectively. Conjugation of the configuration of the disk 2 with the shapes of the rim 1 and hub 3 is done by construction using radius curves.
  • the loads ⁇ R .sup. ⁇ and ⁇ .sub. ⁇ .sup. ⁇ are specified by the graphs of stresses ⁇ R K and ⁇ .sub. ⁇ K as the complex loads are exerted on the wheel during operation.
  • ⁇ R K and ⁇ .sub. ⁇ K are obtained by algebraically summing up the components of the stresses to illustrate their compensation radially of the disk.
  • Tangential stresses ⁇ .sub. ⁇ P at the inside are tensile of about 50 MPa in the center of the disk and 5 to 10 MPa in the transition zones. Tangential stresses at the outside are alternate varying from 10 MPa to 20 MPa.
  • tangential stresses ⁇ .sub. ⁇ S at the inside of the disk are tensile of about 50 MPa in the center of the disk and 5 to 10 MPa in the transition zones. Tangential stresses at the outside are alternate varying from 10 MPa to 20 MPa.
  • the top half is subjected to compressive radial stresses in the order of 100 MPa, whereas the lower half experiences tensile stresses about 100 MPa.
  • the range of variations in the tangential stresses at the outside is from 20 to 50 MPa.
  • the expected pattern of stresses imparted to the disk is obtained by algebraically summing up the stresses from the vertical and side forces, and will be as follows:
  • portion AB compression--30 MPa
  • portion CE compression--100 MPa
  • portion AB compression--110 MPa
  • portion BC compression--100 MPa
  • portion CE tension 80 MPa.
  • portion AB--compression about 40 MPa, at the portion BC--tension, -30 MPa, at the portion CE--compression, -100 MPa; and at the outer side: at the portion AB--compression, -120 MPa, at the portion BC--compression, -120 MPa, and at the portion Ce, tension 50 MPa.
  • FIGS. 4 and 5 show stressed states of the disks of known wheels under the same load conditions. It is seen from the graphs that the range of stress variations in the disks of standard wheels amounts to 200 MPa, in the known wheel it exceeds this magnitude, whereas in the disk constructed according to the invention it is twice as small, particularly about 100 MPa. It follows from the aforesaid that the proposed wheel construction solves the problem of optimizing the quality of railway wheels, as a higher safety extends the service life of wheels, whereas the quantity of metal and labour expended for wheel manufacture can be substantially reduced.
  • Offset of the median longitudinal axis of the disk to a side away from the rim ridge relative to the midpoint of the hub is dictated by that in a wheel having a plane-conical disk half of the length L of the location of the wheel hub at the axle is deformed by the disk as by a calibration ring by the magnitude of the interference fit, whereas in the known prototype wheel more than half of this length is deformed.
  • the stresses ⁇ R .sup. ⁇ at the hub at the outer side of the herein proposed wheel are tensile stresses enabling to take up the clearance between the axle and hub at this side. Therefore, the tightness of fit between the wheel and axle is increased by at least 20% to make the wheel hub susceptible to slipping off, the axle under the action of a complex load.
  • the invention can find application for constructing solid and built-up disk-type wheels of railway trains.
